Description

Vertical wind power generator with drop type blade}

The present invention relates to a vertical wind power generation device, in particular, when the wing member is rotated in the reverse direction from the reverse direction is configured to move forward from one side of the vertical power shaft to the other side to rotate again only in the vertical power shaft The present invention relates to a drop-moving vertical wind power generator capable of maximizing power generation efficiency by wind power.

Wind power generation refers to a power generation method in which wind energy is converted into mechanical energy (rotational power) through a rotating shaft using a windmill, and the mechanical energy is converted into electrical energy by driving a generator to obtain power. It is not only the most economical among the new renewable energy sources, but also has the advantage of being able to generate power using the wind, a clean energy source for unlimited use, and actively invested not only in Europe where the wind power industry was developed but also in the Americas and Asia recently. It is happening.

Particularly, wind power generation has not only cost-effective aspects such as improving the price competitiveness of electric power production costs and minimizing the required area of power generation system, but also the social and environmental aspects such as protecting the global environment such as alternative energy sources and fogging of fossil energy depletion. The government is actively supporting the dissemination of wind power generation due to economic advantages such as the stability of supply and the reduction of dependence on energy imports. Accordingly, it is expected that the growth of wind power generation will accelerate in Korea.

Such wind power generation can be classified into a horizontal wind power generator in which the rotating shaft is installed horizontally with respect to the ground and a vertical wind power generator in which the rotating shaft is installed perpendicular to the ground according to the direction of the rotation axis of the blade. Compared to the vertical type, the horizontal wind power generator is more efficient and stable, so most of the commercial wind farms have been applied to the horizontal wind generator.

The horizontal wind power generator is the most common type, and has the advantage of realizing high power generation efficiency, but it is difficult to smoothly generate power in areas where the wind direction changes frequently, and expensive installation is possible because major components including the rotor are installed at a high level. Not only is it expensive, its maintenance is not easy, and it has a disadvantage that is structurally vulnerable to strong winds such as typhoons.

Compared with the shortcomings of the horizontal wind power generator, the vertical wind power generator can generate power regardless of the direction of the wind. Since the main components such as the gearbox and the generator are installed on the ground, the installation cost is low and the maintenance is performed. Has the advantage of being easy.

Nevertheless, the horizontal power generator is preferred as described above because the vertical power generator is less efficient than the horizontal power generator.

This is a structural problem of the vertical wind power generator, because the blades rotate in a plane parallel to the wind direction, unlike a horizontal power generator in which the blade rotates on a plane perpendicular to the wind direction.

That is, as shown in Figure 15, the vertical wind power generator structurally converts the energy of the wind (W) to the mechanical rotational force of the rotating shaft (b) while one side (a1) of the rotary blade is rotated forward by the wind However, since the opposite side (a2) of the rotary blade to the reverse rotation with respect to the wind will act as a resistance to the rotation of the rotary shaft (b) will have to decrease the conversion efficiency of mechanical energy.

Recognizing the problem of power generation efficiency of the vertical wind power generator, various technical developments have been made to reduce the resistance in the past. It was to receive.

However, since the shape deformation technology of the existing rotary blade has a limitation in reducing the resistance, it is difficult to greatly increase the power generation efficiency. Therefore, it is urgently required to develop a technology capable of removing the reverse resistance to the wind direction.

The present invention has been made to solve the above-mentioned conventional problems, the object of the present invention is to configure the wing member to receive the wind power only forward rotation with respect to the wind power only the forward rotational force by the wind on the vertical power shaft It is to provide a drop-moving vertical wind turbine that can be added to increase the mechanical conversion efficiency.

In addition, a pair of wing seats 25 may be installed on the upper ends of the wing outlets 21 so as to face each other. The pair of wing seats 25 may be upward while suppressing downward rotation in a substantially horizontal state. It can be installed in combination with the rotating shaft so that only rotation is possible (see FIGS. 7 to 9).

Here, the pair of wing seats 25 opposed to each other may be installed at the same height, but adjacent to the track groove 23 so that the wing member 10 can be more easily seated in the track groove (23). It may be desirable to install the wing rest 25b on the opposite side slightly higher than the wing rest 25a on the side.

The guide housing 20 of the above configuration is installed so that it can be freely rotated according to the change in the wind direction irrespective of the rotation of the vertical power shaft 10.

To this end, as shown in FIG. 2, the guide housing 20 may be installed such that its lower side is rotatably supported by a separate bearing structure 26 independent of the vertical power shaft 10, and FIG. 1. As shown in the rear of the guide housing 20, even if the wind direction is changed, the wind direction indicator 27 is provided to provide a rotational force to the guide housing 20 so that the front of the guide housing 20 always faces the blowing wind. Can be.

When the wind direction is changed by the wind direction indicator 27, wind is applied to the wind direction indicator 27 to rotate the guide housing 20 so that the wind direction indicator 27 is parallel to the wind direction. Thus, the guide housing 20 will be able to maintain a constant direction with respect to the wind direction at all times even if the wind direction changes.

Here, instead of the wind direction indicator 27, it is also possible to adopt a method using the automatic wind direction sensor and the motor coming out of the ready-made as a design change by those skilled in the art.

Next, the wing member 30 is a portion that receives the wind power to apply a rotational force to the vertical power shaft 10, the wing member 30 is the wing body 31, the wing rod 32, the wing It may be made of a plate 33.

The wing body 31 may have a cylindrical shape having a predetermined length and diameter as shown in FIG. 6, and is freely rotated inside the body accommodation tool 12 by being supported by the body accommodation tool 12. In addition to being possible, it is possible to move freely along both ends along the body receiving tool (12).

The wing rod 32 is extended to a predetermined length from one side of the wing body 31, such a wing rod 32 can pass through the wing passage 11 of the vertical power shaft (10) It may extend through the track groove 23 of the guide housing 20 to the outside of the guide housing 20.

Here, the support rod 34 may be formed in the wing rod 32, the support protrusion 34 is formed to protrude downward from the bottom of the wing rod 32, the wing body 31 is the number of bodies In the state of being supported by the locking end 13 of the tool 12 (that is, the wing body 31 is completely moved along the body receiving tool 12), the wing rod 32 is the raceway 23 It is formed in a position that can be supported on the outer surface of the guide housing 20 when it extends outward through the passage (see Fig. 10).

The wing plate 33 is provided at the end of the wing rod 32 extending from the wing body 31, so when the wing rod 32 passes through the wing passage 11 together, wing passage 11 together When passing through, and the wing rod 32 extends outward through the orbit groove 23, it receives the wind to act to generate rotational power.

As described above, the configuration of the drop-moving vertical wind turbine generator according to the embodiment of the present invention has been described.

First, the wing member 30 is accommodated at one end side of the body receiving tool 12 in a state where the wing body 31 is supported by the locking end 13, the wing rod 32 is the track groove 23 When the wind is blown in the state extending through the outside, the wind force acts on the blade plate 33 and the wing member 30 starts to rotate along the track groove (23).

When the wing member 30 is rotated along the raceway 23 in this way, the rotational force is applied to the vertical power shaft 10 so that the vertical power shaft 10 is rotated in the forward direction, the power generation is made.

When the wing member 30 continuously rotating along the track groove 23 reaches the wing inlet 22 formed at the rear side of the guide housing 20, the bar blade loses bearing force on the wing rod 32. The member 30 starts to fall and rotate about the wing body 31 by its own weight (see FIG. 11).

When the wing member 30 is rotated in the vertical direction about the wing body 31, the wing member 31 is moved along the body receiving device 12 by the rotational force, so that the wing member 30 is Passes through the wing passage 11 of the vertical power shaft 10 (see Fig. 11).

And after passing through the wing passage 11 is rotated upward through the wing outlet 21 formed on the front of the guide housing 20, a pair of wing rod 32 is provided on the top of the wing outlet 21 The wing seat 25 is pushed upwards (see FIG. 7).

Accordingly, the pair of wing seats 25 are rotated upward while passing through the wing rods 32 (see FIG. 8), and the wing rods 32 are pair of wing seats 25 whose downward rotation is suppressed. The support member 30 is seated on the track groove 23 again while being supported on the track member 23 to start the forward rotation along the track groove 23 (see FIG. 9).

Here, when the wing member 30 passes through the wing passage 11 and exits toward the wing outlet 21, the wing body 31 may not move completely to the other end of the body accommodation tool 12. In consideration of this, the radial increase section 23a is formed in the track groove 23 and the support protrusion 34 is formed on the wing rod 32.

That is, as shown in Figure 10, the wing body 31 is not completely moved to the other end of the body receiving device 12, the wing member 30 is seated on the pair of wing seat 25 and then again In the forward rotation, the support member 34 of the wing rod 32 is supported on the outer surface of the guide housing 20 while the wing member 30 passes through the radial increase section 23a. As the 31 gradually moves toward the other end of the body receiving tool 12, and finally passes through the radial increase section 23a, the wing body 31 is completely moved to the other end of the locking end 13 It will be in a state that takes).

As described above, in the present invention, the wing member 30 is supported by the track groove 23 of the guide housing 20 in the forward direction with respect to the wind direction, and rotates along the track groove 23 to apply the forward rotational force to the vertical power shaft 20. When the wing member 30 reaches the wing inlet 22 of the guide housing 20 before the blade member 30 is rotated continuously and reversed, it is dropped vertically by its own weight and passes through the vertical power shaft 20 to move forward. As it is seated in the groove 23 and rotates forward again, it can be seen that the resistance due to the reverse rotation is completely removed and only the forward rotational force can be continuously applied to the vertical power shaft 10.

In addition, in the present invention, the track groove 23 for guiding the wing member 30 is raised so that the plurality of wing members 30 can rotate at different angles in the horizontal direction, so that they are parallel to each other. It can be seen that the wing plate 33 of each wing member 30 can receive more wind power even if the same wind is blown compared to the rotation, so that a large rotational power can be applied to the vertical power shaft 20.

On the other hand, the drop-moving vertical wind power generator according to the present invention, as described above, since the wing member 30 rotates only on one side portion (forward side) of the vertical power shaft 10, a plurality of vertical power for efficiency enhancement. It becomes possible to be implemented by the structure provided with the shaft 10. FIG.

12 to 14 are diagrams showing an embodiment in which the vertical power shaft 10, the guide housing 20, and the wing member 30 are configured in pairs, and the central power shaft 40 is installed in the middle as shown. The pair of vertical power shafts 10, the guider housing 20, and the wing members 30 may be symmetrically installed on the basis of the central power shaft 40.

And the pair of guider housing 20 can be interconnected to be rotated together in accordance with the change in the wind direction.

In addition, when the pair of guider housing 20 is rotated according to the change of the wind direction, the pair of vertical power shaft 10 may be interlocked so as to change its position.

To this end, as shown in FIG. 13, the lower ends of the pair of vertical power shafts 10 may be installed on the bottom of the pair of guider housings 20 rotatably supported by the bearing structure 26. The pair of vertical power shaft 10 is rotated itself by the rotational force applied from the wing member 30 and the wind direction is changed, the position is automatically changed when the pair of guider housing 20 is rotated It is possible to always maintain the same arrangement as the pair of guider housing (20).

Meanwhile, as shown in FIG. 14, a pair of guider housings 20 in which the pair of vertical power shafts 10 extend upward to support the upper ends of the vertical power shafts 10 so as to be rotatable to the bearing structure 26. It is also possible to install on the upper surface.

In addition, the pair of vertical power shaft 10 is coupled to each other by a gear together with one of the vertical power shaft 10 and the central power shaft 40 by a gear, the central power shaft 40 ) May be connected to the generator 50 through a power transmission means.

In addition, the front connection portion of the pair of guider housing 20 to branch the wind blowing from the front to both sides so as to be incident toward the wing member 30 that rotates along the track groove 23 of each guider housing 20. Wind branch 28 may be formed to protrude forward.

When the wind blows from the front, the wing members 30 coupled to the respective vertical power shafts 10 are rotated in opposite directions along the track grooves 23 of the respective guide housings 20. Independently applying rotational power to the shaft 10, the rotational power of each of the vertical power shaft 10 is to be transmitted to the central power shaft 40 through the gear coupling, through which the power generation efficiency for the same wind power It can be seen that even higher.

As mentioned above, preferred embodiments of the present invention have been described, but the technical scope of the present invention is not limited to the above-described embodiments and drawings, and is modified or changed by those skilled in the art. Equivalent configuration will be made without departing from the scope of the technical idea of the present invention.
